I noticed that we were missing nearly all of our Windows build slaves
this morning, and most of the XP Talos slaves as well. For the past 12
hours or so it's possible that checkins to all branches (except try)
were subject to reduced coverage - slow results, more checkins clustered
together.
Tracking for the acute issue was in

The overall problem is https://bugzilla.mozilla.org/show_bug.cgi?id=522078.
